Abstract

DISPOSITIVO SUPERCONDUCTOR DE PELICULA DELGADA, CARACTERIZADO POR UNA TEMPERATURA CRITICA ELEVADA Y DENSIDAD DE CORRIENTE GRANDE, QUE CONSTA DE UN SUBSTRATO, UNA CAPA DE UNA ALEACION BINARIA POLICRISTALINA, FORMADA POR DOS ELEMENTOS QUE TIENEN DIFERENTES TEMPERATURAS DE FUSION, EN CAPAS SOBRE EL SUBSTRATO, UNA CAPA POLICRISTALINA HECHA DE OXIDOS METALICOS, UTILIZADA COMO UN TAMPON CRISTALINO Y QUE TIENE UNA ESTRUCTURA COMPATIBLE CON LA PELICULA SUPERCONDUCTORA Y UNA CAPA SUPERCONDUCTORA DEL TIPO YBA2CU3O7-X FORMADA SOBRE EL TAMPON. EL OXIDO METALICO Y LAS CAPAS SUPERCONDUCTORAS SON CULTIVADAS POR DESARROLLO EPITAXIAL O CASI REUTAXIAL. LA CAPA SUPERCONDUCTORA SE RECUECE EN ATMOSFERA DE OXIGENO A 800 (GRADOS) C APROXIMADAMENTE.
